Based on the hardware structure, the embodiment of the control method of the air conditioner is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of an air conditioner according to a first embodiment of the present invention.
In this embodiment, an indoor heat exchanger of an air conditioner includes a plurality of refrigerant pipelines, an inlet of at least one of the refrigerant pipelines is provided with a flow regulating valve, and a control method of the air conditioner includes:
step S10, acquiring a current first evaporation temperature of a refrigerant pipeline provided with a flow regulating valve and a current second evaporation temperature of a refrigerant pipeline not provided with the flow regulating valve;
step S20, calculating a temperature difference between the first evaporation temperature and the second evaporation temperature;
and step S30, adjusting the opening degree of the flow regulating valve according to the temperature difference to control the temperature difference to be within a preset temperature range, and dehumidifying by utilizing the temperature difference between refrigerant pipelines.
In this embodiment, as shown in fig. 3, the air conditioner includes a compressor 1, an outdoor heat exchanger 2, a throttle member 3, an indoor heat exchanger 4, and a flow rate adjusting valve 5; the indoor heat exchanger 4 includes a plurality of refrigerant pipelines, the flow control valve 5 is disposed at an inlet of at least one of the refrigerant pipelines, and the flow control valve 5 is not disposed on at least one of the refrigerant pipelines.
Alternatively, a temperature sensor 6 (second temperature sensor) is provided on at least one refrigerant pipe not provided with the flow rate adjustment valve, and a temperature sensor 7 (first temperature sensor) is also provided on the refrigerant pipe provided with the flow rate adjustment valve 5.
When the air conditioner is used for dehumidification, the air conditioner firstly obtains the current evaporation temperature of the refrigerant pipeline provided with the flow regulating valve 5 and the current evaporation temperature of the refrigerant pipeline not provided with the flow regulating valve 5. For convenience of description, the current evaporation temperature of the refrigerant pipe provided with the flow rate adjustment valve 5 will be referred to as a first evaporation temperature T1, and the current evaporation temperature of the refrigerant pipe not provided with the flow rate adjustment valve 5 will be referred to as a second evaporation temperature T2. Alternatively, the current first evaporation temperature T1 of the refrigerant line provided with the flow regulating valve 5 is detected and obtained by the temperature sensor 7 (first temperature sensor), and the current second evaporation temperature T2 of the refrigerant line not provided with the flow regulating valve 5 is detected and obtained by the temperature sensor 6 (second temperature sensor).
After acquiring the current first evaporation temperature T1 of the refrigerant line provided with the flow regulating valve 5 and the current second evaporation temperature T2 of the refrigerant line not provided with the flow regulating valve 5, the air conditioner calculates the temperature difference Δ T between the first evaporation temperature T1 and the second evaporation temperature T2.
Then, the air conditioner adjusts the opening degree of the flow rate adjustment valve 5 according to the calculated temperature difference Δ T. Optionally, the air conditioner sends a corresponding signal to the flow regulating valve 5 according to the calculated temperature difference Δ T, and controls the opening degree of the flow regulating valve 5. The air conditioner controls the temperature difference delta T to be dynamically stabilized at a corresponding set value by adjusting the opening of the flow regulating valve 5, optionally, a corresponding preset temperature range is preset, and the temperature difference delta T is controlled to be within the preset temperature range.
Optionally, a mapping relation between a temperature difference between the refrigerant pipelines and the opening of the flow regulating valve is preset, after the air conditioner calculates and obtains the temperature difference Δ T, the opening corresponding to the temperature difference Δ T is determined and calculated according to the preset mapping relation between the temperature difference between the refrigerant pipelines and the opening of the flow regulating valve, and the opening of the flow regulating valve 5 is adjusted to the opening corresponding to the determined temperature difference Δ T.
For example, if the calculated temperature difference Δ T is small, that is, the temperature difference between the refrigerant pipelines is not large, which is not beneficial to dehumidification, at this time, the opening degree of the flow regulating valve 5 is reduced to increase the temperature difference Δ T, so as to improve the dehumidification efficiency. On the contrary, if the calculated temperature difference Δ T is large, it is also indicated that the temperature difference between the multiple refrigerant pipelines is large, which is beneficial to dehumidification, and at this time, optionally, the air conditioner does not perform response processing.
The temperature difference between the refrigerant pipelines is utilized for dehumidification, and compared with a low-wind refrigeration mode of directly controlling the operation of the air conditioner, the dehumidification efficiency is improved under the condition that the temperature difference between the refrigerant pipelines is basically avoided.
The scheme that this embodiment provided, the indoor heat exchanger of air conditioner includes many refrigerant pipelines, the entry of one of them refrigerant pipeline is provided with flow control valve, when adopting the air conditioner to dehumidify, through acquireing the current first evaporating temperature of the refrigerant pipeline that is provided with flow control valve, and the current second evaporating temperature of the refrigerant pipeline that is not provided with flow control valve, calculate the difference in temperature of first evaporating temperature and second evaporating temperature, and according to this difference in temperature regulation flow control valve's aperture, with the difference in temperature between the control refrigerant pipeline is in predetermineeing temperature range, because evaporating temperature between the refrigerant pipeline is different, form big difference in temperature field in the air around the indoor heat exchanger, the cold and hot air crosses, thereby reach the effect of quick condensation dehumidification, therefore, dehumidification efficiency is improved.
Further, based on the first embodiment, the invention also provides a second embodiment of the control method of the air conditioner. In the second embodiment, as shown in fig. 4, the step S30 includes:
step S31, comparing the temperature difference with a preset temperature difference threshold value, and judging whether the temperature difference is smaller than the preset temperature difference threshold value; if yes, go to step S32; if not, go to step S33;
step S32, reducing the opening degree of the flow rate adjustment valve;
step S33, the opening degree of the flow rate adjustment valve is increased.
In this embodiment, the preset temperature difference threshold corresponding to the opening degree of the flow control valve 5 is preset, and the preset temperature difference threshold can be flexibly set according to actual conditions, and is not specifically limited in this embodiment. After calculating the temperature difference Δ T between the first evaporation temperature T1 and the second evaporation temperature T2, the air conditioner compares the temperature difference Δ T with a preset temperature difference threshold, and determines whether the temperature difference Δ T is smaller than the preset temperature difference threshold.
If the temperature difference Δ T is smaller than the preset temperature difference threshold, that is, the temperature difference between the refrigerant pipelines is not large enough, at this time, the air conditioner controls to reduce the opening degree of the flow regulating valve 5, and further the effect of increasing the temperature difference Δ T is achieved, so as to ensure the dehumidification effect.
On the contrary, if the temperature difference Δ T is greater than the preset temperature difference threshold, that is, the temperature difference between the refrigerant pipelines is relatively large, at this time, the air conditioner controls to increase the opening degree of the flow regulating valve 5, so that the temperature difference Δ T is reduced, the temperature difference Δ T is prevented from being too large, and further the air conditioner is prevented from generating serious condensation.
Optionally, the step S33 includes:
and if the difference value between the temperature difference and the preset temperature difference threshold value is larger than a preset value, increasing the opening degree of the flow regulating valve.
Optionally, a corresponding preset value is also preset, and when the temperature difference Δ T is greater than the preset temperature difference threshold, the air conditioner further compares the difference between the temperature difference Δ T and the preset temperature difference threshold with the preset value. If the difference value between the temperature difference delta T and the preset temperature difference threshold value is larger than the preset value, the air conditioner controls the opening degree of the flow regulating valve 5 to be increased. Optionally, if the difference between the temperature difference Δ T and the preset temperature difference threshold is less than or equal to the preset value, the air conditioner does not perform the response processing.
Optionally, the step S32 includes:
step a, if the temperature difference is smaller than the preset temperature difference threshold value, determining the opening corresponding to the temperature difference according to the mapping relation between the preset temperature difference and the opening of the flow regulating valve;
and b, reducing the opening degree of the flow regulating valve to the opening degree corresponding to the temperature difference.
Optionally, after the air conditioner compares the temperature difference Δ T with a preset temperature difference threshold, if the temperature difference Δ T is smaller than the preset temperature difference threshold, the air conditioner determines to calculate an opening corresponding to the temperature difference Δ T according to a mapping relationship between the temperature difference between preset refrigerant pipelines and the opening of the flow regulating valve, and reduces the opening of the flow regulating valve 5 to the opening corresponding to the determined temperature difference Δ T.
It should be noted that, when a plurality of refrigerant pipelines in the indoor heat exchanger are all provided with the flow regulating valves 5, the air conditioner performs independent regulation and control on the flow regulating valves 5 arranged on each refrigerant pipeline, and specifically, the control operation on each flow regulating valve 5 is as described above, and is not described herein again.
The scheme that this embodiment provided, after calculating the difference in temperature between first evaporating temperature and the second evaporating temperature, the air conditioner is compared this difference in temperature and predetermines the difference in temperature threshold value, judge whether this difference in temperature is less than predetermines the difference in temperature threshold value, if this difference in temperature is less than predetermines the difference in temperature threshold value, then reduce flow control valve's aperture, on the contrary, if this difference in temperature is greater than predetermines the difference in temperature threshold value, then increase flow control valve's aperture, thereby both utilize the difference in temperature to improve the dehumidification efficiency of air conditioner, avoided the difference in temperature too big and lead to the problem that serious condensation appears in the air conditioner again.
Further, based on the first embodiment or the second embodiment, the invention also provides a third embodiment of the control method of the air conditioner. In the third embodiment, as shown in fig. 5, before the step S10, the method further includes:

and step S11, when the operation mode of the air conditioner is a dehumidification mode, acquiring a current first evaporation temperature of a refrigerant pipeline provided with a flow regulating valve and a current second evaporation temperature of a refrigerant pipeline not provided with the flow regulating valve.
In this embodiment, when the air conditioner is running, the running mode of the air conditioner is monitored in real time or at regular time, and the running mode of the air conditioner includes a dehumidification mode, a cooling mode, a heating mode, and the like. When the current operation mode of air conditioner is the dehumidification mode, the air conditioner acquires the current first evaporating temperature of the refrigerant pipeline that is provided with flow control valve 5 to and the current second evaporating temperature of the refrigerant pipeline that is not provided with flow control valve 5, afterwards, according to first evaporating temperature and second evaporating temperature, calculates the difference in temperature of first evaporating temperature and second evaporating temperature, and then according to the difference in temperature, adjusts the aperture of flow control valve 5. The specific operations can be referred to the above embodiments, and are not described herein again.
Further, after the step S40, the method further includes:
and when the operation mode of the air conditioner is not the dehumidification mode, adjusting the flow regulating valve to the maximum opening degree.
Further, when the current operation mode of the air conditioner is not the dehumidification mode, for example, when other operation modes such as a heating mode and a cooling mode of the air conditioner are monitored, the air conditioner controls and adjusts the flow regulating valve 5 on the refrigerant pipeline to be in the maximum opening degree, so that the air conditioner is controlled to efficiently perform operations such as heating and cooling.
